Norton 66252941931 Surface Grinding Wheel 46 Grit 7 in

Product Description

The NORTON 66252941931 is a Type 1 surface grinding wheel designed for precision stock removal on ferrous and non-ferrous metals in industrial grinding applications. Built with aluminum oxide abrasive and a vitrified bond, this wheel measures 7 inches in diameter, 3/4 inches thick, with a 1-1/4 inch arbor hole. It carries a 46 grit, coarse grade rating with an I hardness code (medium hardness range), making it well suited for aggressive material removal while maintaining form. Rated at a maximum of 3600 RPM, it is a dependable choice for surface grinder setups in machine shops and tool rooms.

This wheel is intended for use on surface grinders, cylindrical grinders, and CNC cutting tool machines in both production and maintenance grinding environments. Its aluminum oxide composition and vitrified bond make it appropriate for grinding 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. The porous structure aids in coolant retention and chip clearance during extended grinding passes. It is suited to both wet and dry grinding setups depending on machine configuration.

Key Features

• Type 1 flat wheel profile with no recess — compatible with standard surface and cylindrical grinder arbors
• Aluminum oxide abrasive with vitrified bond for consistent cut rate and wheel integrity
• 46 grit coarse grade delivers fast stock removal on a wide range of ferrous and non-ferrous metals
• Porous wheel structure improves coolant flow and reduces loading during extended use
• Specification designation 32A46-IVBE for cross-reference and replacement sourcing
• Maximum operating speed of 3600 RPM — do not exceed

Compatibility

Rated for use with surface grinders, cylindrical grinders, and CNC cutting tool machines. Suitable for grinding 400 series stainless steel, hard carbon steels, soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. Specification code 32A46-IVBE can be used for direct cross-reference.

Installation Notes

Installation and wheel changes must be performed by a qualified machinist or grinding specialist with the machine fully de-energized and locked out per OSHA lockout/tagout procedures. Always perform a ring test before mounting to check for cracks or damage. Confirm the machine spindle speed does not exceed the 3600 RPM maximum marked on the wheel. Follow ANSI B7.1 safety standards for the storage, handling, and use of abrasive wheels.
